A strain of Steinernemacarpocapsae obtained from overwintering codling mothscollected in Bulgaria was identified to species usingthe polymerase chain reaction. The infectivity ofthis strain towards codling moth prepupae was comparedto that of a U.S. strain at three temperatures (11, 15and 20 °C). Infectivity was low at 11 °C with 8%mortality recorded for both strains. Mortality was61% and 62% at 15 °C, and 82% and 81% at 20 °C forthe Bulgarian and U.S. strain, respectively. The meanpercent mortality at each individual temperature wassignificantly different from each other whenmortalities of the two strains were combined. Thus,the Bulgarian strain did not provide a low temperatureinfectivity advantage compared to the U.S. strain. [ABSTRACT FROM AUTHOR] |
